Fixing of the control of the fan of my car.

Replace the fan assemblies.

That is a VERY easy radiator.
Loosen radiator drain plug and drain coolant from radiator.
Disconnect cooling fan connectorsRemove upper and lower radiator hoses after marking them to ease installation.
For vehicles equipped with automatic transaxles, disconnect transmission cooler lines at transaxle.
Remove air conditioner condenser fixing bolts and radiator bracket fixing nuts.
Remove the radiator, radiator cooling fan, air conditioning cooling fan and transmission cooler lines from the vehicle as an assembly.
Transfer all necessary parts (fan assemblies, cooler lines, clips, speed nuts, fittings, etc.) to the new radiator.

Reverse procedure to install.

Fill and bleed cooling system.

its not worth fixing

Walk around front and make sure the electric fan kicks on when you turn on the air conditioning.
If the electric fan is not kicking on, the most common failure point is the relay. I have never worked on a fan on an e46, but a quick scan of the forums indicates that on this car, there is no relay but there is some sort of control box attached to the fan that turns on the fan based on a signal from the DME.
The complete fan with control box is very expensive, but one fellow reported fixing his electric fan problem with a new fan motor that he got on eBay.

Chek the if the fan works with direct power from battery,if ok check or change fan resistence(fan control)!

If the fans are frozen & won't move then you will need to replace them. However, if they are still capable of moving by you using your hand to just turn them, then you probably have a temperature sensor/fan relay issue. May I suggest that you first identify what is causing the problem before investing in any parts. Then, once you know if it is the fans or the sensor, you'll want to just pressure test the radiator & cooling system to see if there is any leakage. If you only replace the fans & the radiator without fixing another problem, you'll just have to start all over again. To check just the cooling system (from cold engine), fill up the radiator to where it should be, along with the overflow tank to the low line & put the cap back on & start the car long enough to see if there is a leak anywhere. If not, you only need to focus on fixing the problem with the fans. Generally this is the "cooling fan sensor" that mounts near the bottom of the radiator. Some models have the sensor near the thermostat housing, some on the top of the radiator, & some on the bottom of the radiator. A good Haynes manual for that specific car will save you time & trouble with just a simple 5.99 voltage tester.

Good Luck!

Most likely caused by faulty blower fan speed control resistor module.
This unit is usually located in the heater air ducting under the dash ( in the blower fan airflow ) - unplug and remove fixing screws to replace.

That sounds to me like your vent "tubing" is disconnected somewhere along the line. I am not sure exactly how it is set up in the vehicle you are driving, but I am certain fixing it will involve taking apart most all of your interior then putting it back together after a 10 minute fix.

Sound like you have a bad cv "constant velocity joint " REPLACE.

The first thing you need to do is to clear your old codes then drive

and see if they come back .

1. Re-enter back into the climate control panel and after all the codes display the display will stop at PCM?

2. Push and release the FAN UP (^) button on the climate control panel and you will see PCM DATA?

3. Keep pushing and releasing the FAN DOWN (v) button until you see PCM CLEAR CODES?

4. Push and release the FAN UP (^) button and you will see PCM CODES CLEAR?

5. Wait 5 seconds and then keep pushing the OFF button until you see PCM?

6. Push and release the FAN DOWN (v) button and you will see IPC?

7. Push and release the FAN UP (^) button on the climate control panel and you will see IPC DATA?

8. Keep pushing and releasing the FAN DOWN (v) button until you see IPC CLEAR CODES?

9. Push and release the FAN UP (^) button and you will see IPC CODES CLEAR?

10. Wait 5 seconds and then keep pushing the OFF button until you see PCM?

11. keep Pushing and releasing the FAN DOWN (v) button and you will see ACP?

12. Push and release the FAN UP (^) button on the climate control panel and you will see ACP DATA?

13. Keep pushing and releasing the FAN DOWN (v) button until you see ACP CLEAR CODES?

14.Push and release the FAN UP (^) button and you will see ACP CODES CLEAR?

15. Wait 5 seconds and then keep pushing the OFF button until you see PCM?

16. keep Pushing and releasing the FAN DOWN (v) button and you will see SIR?

17. Push and release the FAN UP (^) button on the climate control panel and you will see SIR DATA?

18. Keep pushing and releasing the FAN DOWN (v) button until you see SIR CLEAR CODES?

19. Push and release the FAN UP (^) button and you will see SIR CODES CLEAR?

20. Wait 5 seconds and then keep pushing the OFF button until you see PCM?


21. Push the AUTO button to get out of diagnostics.

22. Turn ignition OFF for 15 seconds.

23. Re-enter diagnostics and see if any history codes re-appear.

could be a fuse they are located behind the ash tray. could be the fan motor you can test this by finding the connection for the fan motor and connecting a positive and negative wire to the positive and negative on the connector. it could also be a relay or loose or bad connector . start at the fuses check all of them. then check to see if your fan works then check all your connections if that is not it try to see if any of your relays look burned. im not sure whicjh one controls the fan controls. good luck if you need more help or specifics i will look into it more i have a friend with one of these vehicles that i can look at.
